Below, with reference to above-mentioned accompanying drawing most preferred embodiment of the present invention is described.
(1) structure of reinforcing bar stair
Used reinforcing bar stair 8 are by going downstairs 3 and go upstairs and 6 constitute as the stair of a floor in present embodiment, go downstairs 3 to be made of stair portion 1 and landing 2; Go upstairs 6 by stair portion 4 and (stair) landing 5 formations.Landing 7 (referring to Fig. 1) in the middle of constituting by go downstairs 3 landing 2 and 6 the landing 5 of going upstairs.3 the 1 lower end 1a of stair portion of going downstairs is configured on the floor of benchmark floor, and the upper end 4b of 6 the stair portion 4 of going upstairs is configured on the floor of the direct last layer of benchmark floor.
(2) structure of the supporting arrangement of stair
As the corner part of constructing predetermined staircase, when constructing predetermined staircase, the ground side between the stair ladder, two pillars 10 uprightly are embedded in the wall portion of staircase side by side.The height of these two pillars 10 is taken as the height of regulation, and the height of for example getting into predetermined stair partition portion is (if construct a floor, the height of the floor as usefulness H among Fig. 1 (b) shown in then; If construct multilayer, then be) as using the several times of the story height shown in the H among Fig. 1 (b).
The both ends 13,13 that can support the supporting beam 12 of reinforcing bar stair are separately fixed on the position of the fastening predetermined reinforcing bar stair end in two pillars 10 (with reference to Fig. 4 (a)).Wherein, if height one story height of two pillars 10 then is fixed to the both ends 13,13 of supporting beam 12 the height position of a floor shown in Fig. 9 (a); If the height of two pillars 10,10 is height of many floors, then shown in Fig. 3 (a), the both ends 13,13 of many supporting beams 12,12 are separately fixed at the height place of each floor.
Then, the installation component 16,16 with flange 18a in two pillars 10, be separately fixed on half height and position of the story height on the pillar 10.Then, configuration is provided with beam 17 temporarily between above-mentioned flange 18a, there is flange 18 at these both ends that beam is set temporarily, with bolt, nut the flange 18a that is fixed on the pillar 10 are fixed (referring to Fig. 5 (a) and (b)) with the flange 18 that is provided with on the beam 17 temporarily.Since be with bolt, nut form fixing, thereby just can be installed in the both ends that beam 17 is set temporarily between pillar 10 and the pillar 10 with unloading and be on half position of an above-mentioned story height.Have at pillar 10 under the occasion of many story heights, by the height of each floor, on pillar 10, fix many supporting beams 12 as described above, in abutting connection with the height place of the substantial middle of the height and position of the supporting beam of fixing 12, the both end sides that beam 17 similarly will be set temporarily can be installed on the pillar 10 with unloading up and down.
An above-mentioned so-called story height roughly half height and position, in Fig. 1 (b), be meant with the height about highly half shown in the H in abutting connection with the height and position of the substantial middle of the height and position of the supporting beam 12 fixed of ground up and down; In Fig. 3 (a), be meant in the many supporting beams 12 that are fixed on the pillar 10, the height of the intermediate degree of the supporting beam 12 of adjacency up and down.These roughly the height of half height, substantial middle by going downstairs 3 and go upstairs and 6 have what kind of height dimension respectively and determine, promptly, because when a story height H being regarded as one regularly, 3 height dimension increases if go downstairs, 6 the height dimension of then going upstairs just dwindles, thereby the height of above-mentioned roughly half height, substantial middle compares with half height just in time, becomes a little the height by upside; If go downstairs on the contrary 3 reduced height, then because 6 the height dimension of going upstairs increases, thereby the height of above-mentioned roughly half height, substantial middle compares with half height just in time, become a little height by downside.
As mentioned above, when constructing staircase,, constituted the supporting frame 14 (with reference to Fig. 3 (a)) that is embedded in the staircase wall in the ground side of staircase.
As mentioned above, make stair side surperficial corresponding of flange 18, the residing position of 18a and predetermined staircase wall.Promptly, beam 17 being set temporarily is to be installed on the pillar 10 exposing in the position of stair side from the surface of the reinforcing bar stair side of predetermined staircase wall.
Then, as the staircase corner part, when constructing predetermined staircase, in the staircase wall of the landing side relative, uprightly bury two pillar 10a underground side by side with the staircase ground side, with being installed on the pillar 10a that formation supporting frame 14 similarly can unload the two ends of supporting beam 12a, constitute supporting frame 15 thus.
The difference of supporting frame 14 and supporting frame 15 only is in this, promptly, in supporting frame 15, with supporting frame 14 in fixed bearing beam 12 the height and position corresponding section, beam 17a will be set temporarily be installed on the pillar 10a; With the installation in the supporting frame 14 be provided with temporarily beam 17a the corresponding height of height place, supporting beam 12a is fixed on the pillar 10a.
As mentioned above, upright side by side respectively pillar 10 and the pillar 10 that is provided with must be opened the horizontal amplitude (L that can hold the reinforcing bar stair 8 shown in Fig. 1 (a) by sky 1) upright the setting.The pillar 10a of supporting frame 15 and the interval of pillar 10a also will separate equally.
As described above, the supporting frame 14 that constitutes respectively and supporting frame 15 skies are opened length L with reinforcing bar stair 8 direct of travels 2(with reference to Fig. 1 (a)) relative interval, promptly, make and in Fig. 2, use L 3Shown length at interval in, can accommodate among Fig. 1 (a) by L 2Shown in the length compartment of terrain supporting frame 14 and supporting frame 15 (with reference to Fig. 6) erectly are set side by side.
As mentioned above, constitute the supporting arrangement of stair of the present invention.
13 places, end at supporting beam 12,12a, with predetermined corresponding position, staircase wall surface position on fixing closure plate 20 (with reference to Fig. 4 (a) and (b)), common, above-mentioned each root supporting beam 12,12a and using shaped steel, because supporting beam 12,12a connect the wall mould plate that concrete pouring is used, thereby process easily for the mould plate that makes this part, closure plate 20 is set.Though only represent supporting beam 12 on Fig. 4 (a) and (b), also fixing closure plate 20 on same position at supporting beam 12a place.
In the present embodiment, the supporting beam 12 of the adjacency up and down in supporting frame 14,15 and beam 17, supporting beam 12a are set temporarily and are provided with between the beam 17a temporarily is installed with tie rod 21 (referring to Fig. 3, Fig. 4, Fig. 5) across.Between tie rod 21, adorning turnbuckle (not having expression among the figure), may adjust the length of tie rod 21 by it.
Only in framework C tie rod is being set on the supporting frame 15, the upside of framework C has supporting beam 12a, downside and has beam 17a is set temporarily.Though on the less framework of other load burden, tie rod 21 is omitted (referring to Fig. 3 (b)), also can all in the framework tie rod 21 (not having expression among the figure) be set all.
And for example shown in Fig. 4 (a), Fig. 5 (a), the end 22 of tie rod 21 is installed in supporting beam 12,12a respectively, and the staircase wall surface distance from predetermined that beam 17,17a are set temporarily is the position of L.Though Fig. 4 (a), Fig. 5 (a) only represent supporting beam 12, beam 17 are set temporarily, to supporting beam 12a, beam 17a to be set also be same temporarily.Here distance L be place at this position scaffolding board, operating personnel with it as path and can be by the distance at this position, though to get usually about 50cm from the safety consideration, in order to place 1 scaffolding board, about minimum desirable 30cm.
Can be according to different conveying situations, it is (being generally about 3～4m of specific length that above-mentioned pillar 10,10a are resolved into every, make generally that it is corresponding with prefabricated story height), in conjunction with the end, fixing flange 11,11 (referring to Fig. 3 (a) and (b)).And tie rod 21 is avoided the position of this decomposition certainly.Can be with the pillar 10,10a, supporting beam 12, the 12a that disperse, beam 17,17a, tie rod 21 etc. are set temporarily and make member, be transported into the building site, constitute supporting arrangement 21 with bolt, nut assembling back.
Though be that the section configuration of above-mentioned pillar 10,10a is made shape in the wall that can be embedded in staircase when constructing in such scheme, but make the occasion that double reinforcement disposes, the section configuration that can between two reinforcing bars, hold on the wall thickness direction of then making at the reinforcing bar that wall is used.Be under the occasion of D at wall thickness for example, the bore of reinforcing bar is about 1.5cm * two piece, and the overburden cover of affix reinforcing bar is about a position, 3cm * 2, section configuration must be made can be contained in below " D-9cm " on the wall thickness direction.For example, wall thickness is the occasion of 18cm, and the length of the section of pillar 10 on the wall thickness direction is below the 9cm, preferably gets into below the 6cm.In addition, under single reinforcing bar configuration occasion, to consider reinforcing bar and overburden cover too, section configuration be made the shape that can not hinder configuration reinforcement in wall.
In the present embodiment, owing on supporting frame 14,15, used tie rod 21, thereby the section configuration of necessity of pillar 10,10a is dwindled, it can be made the shape in the wall that can easily be embedded in staircase.
On the other hand, under the occasion in the section configuration with pillar 10,10a expands the wall that to a certain degree still can easily be embedded in staircase to, perhaps when not using tie rod 21, still can guarantee tie rod can be omitted under the occasion of certain intensity.
(3) stair and staircase constructs
1. on the good concrete benchmark floor concrete floor 26 of cast, supporting arrangement 24 is set erectly, with pillar 10,10a be fixed on benchmark floor concrete floor 26 (or down one deck pillar 10,10a upper end in conjunction with end flange 11,11,11,11) on.
Usually supporting arrangement 24 uprightly is set to the height (referring to Fig. 9 (a)) of the reinforcing bar stair that can construct first floor.If but supporting arrangement 24 is more than the height of a floor, then also can be according to the construction degree at scene, supporting arrangement 24 is made height more than 2 layers or 3 layers; If supporting that can be suitable, it is such also can to make whole floors (being 6 floors in Fig. 3) height overall.
Preferably make the upper end of pillar 10,10a be projected into the top (referring to Fig. 9 (a)) of predetermined concrete floor 35 in conjunction with height and position with flange 11.
